This EASY LOW CARB BUFFALO CHICKEN STUFFED SPAGHETTI SQUASH is always a winner when we serve it at our house. We take fresh spaghetti squash and chicken breasts and cook them on a sheet pan. We shred them and mix them with all of the ingredients you love for buffalo chicken dip and serve them back in the squash boats for a beautiful and delicious meal!

It is no secret that I love all kinds of squash. I have lots and lots of squash recipes here on the site. Just use the search function and you kind find anything you would like. Squash is such a good vegetable. You can make it sweet or savory and even sometimes, eat the skins for added nutritional value.

This easy, low carb, buffalo chicken stuffed spaghetti squash is one of my favorite things to make. One of my favorite crock pot appetizers is our CROCK POT BUFFALO CHICKEN DIP and this one is so close to that! We only add in more vegetables and sub greek yogurt for added health benefits and more protein!

Ingredients

We use simple, staple ingredients for this one. Lean chicken breasts, one spaghetti squash and a few creamy and spicy components for a cheesy goodness with a slight kick!

What You’ll Need

  • Spaghetti Squash- we use a whole one here so I suggest getting a pretty large one to feed lots of people.
  • Chicken Breasts – use can use other cuts of chicken here but to keep it low carb we always use the breast.
  • Riced Cauliflower – just a little and you won’t even be able to tell its in there! One more veggie under your belt!
  • Shredded Cheese – we like pepper jack for this one since it is buffalo chicken!
  • Hot Sauce – use your favorite here, just make sure it doesn’t add any sugar to the recipe.
  • Unsweetened, Plain Greek Yogurt – a creamy burst of protein!
  • Salt and Pepper – nothing fancy, we let the hot sauce and cheese do the heavy lifting.
  • Green Onion – we use a bit in the mixture and some for garnish so remember to reserve a bit for a pop of color!

Want to save this recipe?

We'll email this post to you, so you can come back to it later!

  • SQUASH – you can use most any winter squash and cook and remove the flesh and mix with the other ingredients, stuff the skins and make something similar but entirely new.
  • GREEK YOGURT – sour cream is a good sub here or even a mixture of sour cream and cream cheese that has been softened. These will make this even creamier!
  • RICED CAULIFLOWER – grated zucchini that has been drained well or even finely chopped broccoli. Both would add lots of color and nutritional value to this recipe.
  • CHEESE – we use pepper jack to add a bit of spice but feel free to use cheddar cheese or any good flavored cheese you like here.
